Application filed January 2, 191?;8. Serial No. 409,023. I

To all whom. it may concern:

Be it known that 1, JOHN Ross, a citizen of the United States, residing at Landlock, in the Districtof Alaska, have invented certain new and useful Improvements in Ore- Chutes; and I do hereby declare the following to be a full, clear, and exact. description with auxiliary we of the invention. Slir'l) as will enable others skilled in the art to which it appertains to make-and use the same.

This invention relates to improvements in chutes and nice ianism for regulating the action thereof and particularly to chutes designed to convey material in hulk us crushed ore, sand and the like.

The invention comprises the. provision of a chute formed near the lower end thereof with guiding means for necouuuodarting a gate together with n lei-er and connecting mechanism for operating the gate or door for regulating the flow or" material through the chute The invention further comprises the provision of e. chute formed with ways secured to the wells thereof and hmeine' means for holding said ways i ll in position to ether .1 for forming: an extension V to the first mentioned way so that ngate or chute or for re door moving in the said ivays may he ontirelg' removed 1' min. the chute.

e ohject. in View is the provision of u" chute formed '5 1 means for' permitting loose material in oulk to pass through the chute or to shut oi. same as may he desired without moviin, the position of the chute.

Another object in view is the provision ofuv chute formed'wih guide wuysand lever mechanism for moving a gate across said i ing a. gate or door from nuiy he desired.

across the" chute With these an" oil-er ohjeeis in view theinvention coin -es certain eon-urnvtions, combination an: arrungtunent of parts that will he. llGlfi-llltlfi?! more fully (lPSCZllJCd and explained.

In the accompanying drawings: Figure 1 is a perspective fragmentary view of achute with my invention secured thereto. Fig. .2 is a f ragmeni a i; sectional view on line 2--2 of 1. Fig. 3 is a section through one of the guiding and reinfort-ing means forming part of the presentin ention'tlre some being taken approximately on line 3-3 of .ig. 1.

In the use of chutes it has been found de simble to provide a door for stopping temporarily the flow of material through the chute. Various means have been provided for operatin the door quickly and'as often as desiret'l.

operated as often as desired and at. the'eXa-et time desired that the present invention relates.

It is more particularly to the class of invention in wlnrn the door may be Referring more particularly to the-drawing, 1 indiemesa chute oi nny desired kind bolts holding reinforcing and hearing memhers 4 and Sin place pass through the sides.

of chute l and throng 1 ways 2 and 3. The ways 2 and are preferably made, of flat, mm of any desired size. as eleerlv seen in Figs. 1 and 3 end members 4 and euro also formed of angle irons designed to he riveted or bolted together. The irons forming way 3 extend down to tinge the lloer or bottom 6 of the chute 1. The R- forcing member 5 as clearly seen in Fig. 2 tom 6 to any desired distanceand has socured thereto angle irons 7 that-form a continuntion of way 3, n being out in bOir tom 6 f or permitting are ntinuous way to he formed for door or s r to operate in. Way 2 is constructed s I has, an extension, a. irons Q that form continuation of way 2. Brace or reinforcing member 4, as clearly see-n in Fig. 1, ex tends down any desired di tance for reinforcing and holding in pos"'n angle irons 9 forming an extension-of we 2. Door-8 is uedto slide in ways 2 end 3 and their extensions so as to he glfirillflnell across the chute 1 and prevent" the flow of any material therethrough or he moved to a position in the extended ways 2 and 3 fouled by angular irons 7 and 9. By this enstruction door 8 C is permitted avertical movementor a. movemcnt directly across t chuteso that when itis desired to close oi? the low of material us that are pivettends beyond hot- .11- to way 3 and ally swung across the chute or forced downvertical extension for said wavs,

wardly into the chute as the resistance to the movement of the door decreases as it moves to the position shown in Fig. 1. If a slide is forced down from above the material would have to be forced aside by the door as it neared the bottom rather than simply stopping the flow of the material as it does when it enters from the bottom and passes upward.

In order to provide means for easily moving door 8 to an entirely closed position "as shown in Fig. l, a partiallyclosed positron, or an entirely open position as shown in dotted lines in Fig. 1, a lever mechanism is provided. Various lever mechanism may be provided within thespirit of the'invention but in order to disclose one form of the invention I have shrnvn a lever 10 that is formed of a bar bent substantially at right angles. After bending the bar is for ned with what may be termed a'handle 11 and a lever 12. T e handle 11 and lever 12 are connected by a link 13 for. preventing the lever or member 12't'0 be moved out of its correct position in relation -to handle 11.

The lever 10 is pivotally mounted in a ful-' crum or journal member" 14 that in turn is mounted in any desired kind of support 15. Pivotally secured to the outer end of lever 12 is a connecting rod or link 16 that in turn is ivot'ally secured to door 8 by journal memiier 17;

When it is desired to open door 8 the handle 11 is forced over to the position shown in dotted lines in Fig. 1 and as a result link 16 is pulled downward, consequently door 8 is moved in ways 2 and 3 until it has left the chute 1 entirely free. for the passage of material therethrougb. \Vhen it is twain desired to close or partially close door 8 handle. 11 is )ulled back to the position shown in full iines in Fig. 1 or to any intermediate position and door 8 will be moved according to either a full closed position or a partially closed position.

What I claim is:

1. In a chute, the combination with a chute prooer, having side walls and a bottom section, 0 ways positioned intcriorly on said walls, angle llOIlS positioned extertorly. on said walls forming a bracing thereof and a l l i i z i a ehu te section extending away from said ways pro vided with an opening in its bottom port-ion inline with said ways, a gate slidablymountcd l in said ways, a link pivotally connected with said g.-tte, a lever pivotally engaging said link, and independent means for supporting said lever.

2. In a chute having side walls and a bottom section, ways yertically positioned on said side walls and away from the end of said chute, downwardly extending braces formed of angle bars exteriorly positioned on said side walls and forming an extension for said ways, a gate slidably mounted in said ways, a

link pivotally=secured to said gate, and a levtrr independently supported and pivotally connected to said link for operating said gate.

3. In a device of the character des ribed, a chute, guide ways formed therein, reinforcing members, auxiliary guide ways secured to said reinforcing members and forming an extensioi of said first mentioned guide ways, a door designed to operate in said guide ways, and menus for ouerating said door.

4.5111 a chute raving side walls anda bottom section provided with an opening away from the end thereof, ways interiorly positioned on said side walis in line with said bottom opening, braces cxteriorly positioned on said side walls and forming downward extensions for, said ways, a door adapted to slide in said ways, and means connected to said door for moving the. same.

5. in a chute having side. walls and a bottom section provided witlran opening positioned a short distance from the end thereof, w n's'verticully positioned on said side 'alls, brat es l'oru'iiug a downward extension for said ways, a gate slidable in said ways, an inclined discharge section extending away from said ways, a link )ivotally mounted on said gate, an imlepend ently su )ported L shaped lever opcratively connector to said link and adapted to downwardly withdraw said gate from said chute.

In testimony whereof I'aliix my signature in presence of two witnesses.

J OIIN ROSS.
